Case Study: All Nippon Airways achieves scalable, high‑deliverability flight notifications with SendGrid

Twilio SendGrid Supports the Largest Aviation Infrastructure in Japan

All Nippon Airways (ANA), Japan’s largest domestic carrier with a global network, needed to modernize its flight‑irregularity notifications. The legacy system struggled to scale for short‑term spikes of hundreds of thousands of messages and to support new channels like SMS and app push while ensuring timely, polite communication during delays and cancellations.

ANA implemented Twilio SendGrid (API and SMTP) to build an API‑based, scalable notification platform. With clear documentation, rapid development (3–4 months), deliverability support and IP warm‑up guidance from SendGrid, ANA now reliably sends high‑volume alerts, segments users with Subuser accounts, and reports a 97.7% deliverability rate and a 0.095% average bounce rate, enabling ongoing channel expansion.
